7.Graph the piecewise function foo)= = = and then determine f (-4). 8. Consider the function f (x) = x* - 12x + 3 . Determine the vertex by completing the square. Solve for the intercepts and graph the function (label the vertex and intercepts on your graph) 9. Simplify cos ( x + )+ sin (x -) 10.a. Perform the indicated operation. Indicate the quotient and remainder 23 - 1 b. Use part a. to determine if 2x - 1 is a factor of the polynomial f (x) = 483 - 3x2 _ 2 - 6x + 1. 1 1. Graph f (x) = - In(x + 2). State the x and y intercepts, if any, State the equations of the asymptotes, if any
